Integrated anti-accident drilling simulation system of power grid

ZHENG Xincai,LIU Chengwei,QIN Sanying,YANG Sumei(Shangqiu Power Supply Company,Shangqiu 476000,China)  
The integrated anti-accident drilling simulation system for Shangqiu power grid is presented,as a cross-platform simulation support system,which is composed of real-time database management system,real-time execution and procedure dispatch system,procedure communication and I/O execution system and so on.Compared with traditional real-time database,the ability of abstract data configuration management is enhanced.The real-time fault power flow analysis technique of asymmetric network is adopted in the primary model of power grid to dynamically calculate the fault voltage of each node and the fault current of each branch and to directly start up the protective relay and automatic equipment.The protective equipment of the secondary model of power grid is the same as that of real power grid,of which the current and voltage are sampled via PT and CT,calculated according to protection principle and compared with the settings to realize protective functions.The graphic protection panel is adopted to present its real configuration and to realize all site operations.The simulative module of substation device adopts the three-dimensional animation to show the actual substation.All items of field operation order are realized in the simulation system.The system has various functions of online dispatch automation system.The system realizes the combined anti-accident drilling integrated of power grid and substation and the multiple functions for training and technical contest of operators,dispatchers and protection staffs.
